COMTBINATIO'N LOCOMOTIVE AND OOAGEEZ HOIST.

Application filed May '7, 1921. Serial No. $67,734.

To all whom it may concern Be it known that I, SIDNEY T. SJonnRe, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented a certain new and usefulImprovement in Combination Locomotive and Coach Hoists, of which thefollowing is a specification.

This invention relates to mechanism adapted for installation in carshops, selectively usable for lifting car bodies, which ordinarilyneither require nor permit the use of a cross beam or girder under thecar body, off from the car truck or for lifting a locomotive whichbecause of its weightnecessarily requires a cross girder ext-endingvover the rails and under the locomotive body.

Devices have heretofore been constructed, such for instance as shown inPatent No. 1,- 349,324 to A. H. McDougall issued July 13, 1920, adaptedto travel along a supplemental track on the side of a track, and whenproperly actuated hook under the edge of the car to lift it off from itstruck. The object of this invention is to provide a construction ofgeneral application with reference to a railroad track on which the caror locomotive to be lifted travels and to equip it with mechanism of theclass just referred to, so modified that with or without the presence ofother mechanism entering into this invention the combined mechanism maybe selectively used for lifting a car or a locomotive.

The invention consists in means for carrying out the foregoing objectswhica can be easily and cheaply made, which is satisfao tory in use, andis not readily liable to get out of order. More particularly the invention consists in features and details of construction hereafter morefully set forth in the specification and claims.

Referring to the drawings in which similar numerals represent similarparts thruout the several views,

Figure 1 is a face view of one form of mechanism illustrating thisinvention having a beam lying across the railroad track for the purposeof lifting the locomotive.

Figure 2 illgustrates the right hand half of themechanisin of Figure 1applied to the lifting of a car which has been substituted for alocomotive of Figure 1.

Finjure 3 is a side detailed View taken on the line 33 of Figure 1,showing a jib crane mounting.

in carrying out this invention the designer of the repair shop or otherlocality where the device is to be used, provides a concrete or othersuitable base structure having a central portion 10 suitably supportingtrack s 12 on which car or locomotive wheels are adapted to travel andhaving on each outside the i ls 12, suitably shaped proport oned pits 16carrying at their ack ralls 18 on which truck wheels travel parallel tothe railroad rails 12. Outside oil? the pit 16 the constructor usually.0 c .L

cross a working floor 24- in general on a level with the rails 12.

At least four trucks 22 should be ordi- 'ily privided, two on the rails18 on each side of the rails 12, one at each end of the car orlocomotive. Conventionally rising from these trucks 22 are verticalmasts 26 within which are lifting screws 28 suitably driven by anysuitable means as for instance worm wheel. mechanism 30, all as morefully suggested in said prior patent Furthermore, as there suggestedeach ma st 26 is provided with a lifting screw 28 adapted to elevate anddepress laterally projecting load carrying hooks 32. Each hook isadapted to selectively hook under the ends of a cross beam 34-insertable over the rails 12, under the locomotive 36 to directly engagesome part of the locomotive, as for instance the cylinders 38, and isalso selectively useable to engage the lower corner 40 of a car bod asshown in Figure 2, and lift it off from the mechanism 1-2 which isordinarily of such a structure that the beam 34 can not be used under acar body.

In the use of tiis particular form of the invention the pit 16 should bemade so low that hooks 32 may descend low enough into them to allow thebeam 3a to be inserted load lifting trucks 22 are adapted strength forlifting a locomotive in the relatively narrow space below thecontactable parts, say the cylinders 38.

For convenience in handling cross beam 234i. it is desirable that themasts 26 on at least one side of track 12 be equipped with a swingingjib crane l4 suitably pivoted at 426, and braced by a rod 48 in theconventional. manner so that a tackle mechanism 50 may be suspended fromthe crane and readily applied to the beam 34 as for instance by hooks@ne method 0t operating the device is to assemble in front of or behindthe locomotive a pair of jack mechanisms as shown in Figure l with beamacross their hooks 32 and then by means not entering into this inventionmove the truck bodies 22, carrying the beam to proper position under thelocomotive, and then by mechanism not entering into this inventionmanipulate the screws 28 to elevate the beam 34 and consequently thelocomotive.

In the case of a car to be lifted, each truck 22 is manipulatedindependently to position it under the car edge 40 and then to raise theadjacent portion.

laying thus described my invention, what I claim as new and desire tosecure by Let ters Patent, is:

1. ln mechanism of the class described, a base having on opposite sidesthereof parallel pits, railroad car tracks on the base, truck carryingtracks in. the pits, parallel to the railroad rails, a jack carryingtruck on each of the last mentioned tracks, a jack mechanism on eachtruck, a hook on each jack mechanism movable vertically, and adapted tohook under the edge of a car body of a car traveling on the railroadtracks, a beam insertable across the railroad tracks and supported bysaid hooks, the whole being so arranged and proportioned that the loadcarrying hooks can descend far enough into the pits so that the beampractically contacts the railroad track rails.

2. In mechanism of the class described, a base having on opposite sidesthereof parallel pits, railroad cartracks on the base,

truck carrying tracks in the pits, parallel to the railroad rails, ajack carrying truck on each of the last mentioned tracks, a jackmechanism on each truck, a hook on each jack mechanism movablevertically, and adapted to hook under the edge of a car body of a cartraveling on the railroad tracks, a beam insertable across the railroadtracks and supported said hooks, the whole being so arranged andproportioned that the load carrying hooks candescend far enoiigh intothe pits' 'so that the beam practically ,cqil acts the r lroa tl trackrails, and a crane mechanism transportable by one of the trucks toliftisaid beam off from and on to the hooks, for the purposes set torth.

3. In mechanism'of the class described, a supporting base for railroadtrack rails intermediate between parallel pits provided with rails ofsupporting load lifting truck mechanism, load lifting hooksreciprocatable vertically by the load lifting truck mechanism, andadapted for depression into the pits to a point where a beam laid acrossthe railroad track rails over said hooks is substantially on a levelwith the tops ofth e railroad track rails,

In witness whe t, I have hereunto subscribed my name n the presence oftwo witnesses.
